Description of problem:
The file /usr/src/linux-2.4/include/linux/iobuf.h has been changed between
2.4.18-3 and 2.4.18-5 and one of the members of the struct kiobuf (map_array)
has been removed (look at both files near line 53). Since it hasn't been
removed from the linux 2.4.19 I assume this was a mistake. It has also been
removed from linux-2.4/fs/iobuf.c.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install RedHat 7.3.
2.Use up2date to upgrade to kernel 2.4.18-5 (from default 2.4.18-3).
3.Notice that "map_array" is gone from
/usr/src/linux-2.4.18-5/include/linux/iobuf.h. (it *was* in corresponding
Actual Results: map_array is gone.
Expected Results: map_array should not be gone.
the recoding of the kiobuff is actually a performance enhancement (the kiobufs
become leaner and use less memory/cache)
